Embodiment Construction

[0027] See attached Figure 1 to Figure 4 , providing a linear displacement override rod structure, characterized in that: comprising an inner cylinder 1, an outer cylinder 2 and a braking device;

[0028] One end of the inner cylinder is the connecting end of the aircraft joystick system, one end of the outer cylinder is the connecting end of the aircraft joystick system, the other end of the inner cylinder is plugged together with the other end of the outer cylinder to form a package structure, and the inner cylinder and the outer cylinder are sliding fit ;

[0029] The braking device is fixed on the outer cylinder, and the braking device exerts a limiting force between the inner cylinder and the outer cylinder, so that the inner cylinder and the outer cylinder will not slide against each other, forming a rigid connection and maintaining a locked state; when applied to the inner cylinder and the outer cylinder When the push or pull force between the outer cylinders is great...

Abstract

The invention relates to a linear displacement override rod structure, which comprises an internal cylinder, an external cylinder and a brake apparatus; one end of the internal cylinder is an airplaneoperating lever system coupling end, one end of the external cylinder is the airplane operating lever system coupling end, the other end of the internal cylinder is inserted with the other end of theexternal cylinder, and a sleeving structure is formed, the internal cylinder and the external cylinder realize sliding fit, the brake apparatus is fixed on the external cylinder, the brake apparatusapplies restriction force between the internal cylinder and the external cylinder, so that the internal cylinder and the external cylinder are mutually slid, and rigid connection is formed. A combination mode of a torque limiter and rack-and-pinion realizes linear displacement override, an axial length is short, weight is light, the linear displacement override rod structure is suitable for installation in a small space, disengagement while override is rapid, residual stress after disengagement is small, driver control burden is greatly mitigated, artificial reset can be carried out at ground,maintenance performance is good, reliability is high, service life is long, and security and control quality for airplane control are increased.

Description

technical field [0001] The invention belongs to the technical field of aircraft control system design, and relates to a linear displacement overriding rod structure and a method thereof, in particular to a linear displacement overriding rod structure of a control rod system between pilots and co-pilots of an aircraft. Background technique [0002] In the aircraft control system, the pilot and the co-pilot are mechanically interconnected through the override mechanism, and the synchronous movement between the pilot and co-pilot linkages is realized during normal operation. When the pilot (or co-pilot) linkage fails, the The pilot on the other side can disconnect the joystick system on the jamming side after overcoming a certain threshold starting force to realize overriding, and then the non-jamming side can still control the aircraft, thereby improving the safety of aircraft control . [0003] The existing linear displacement override method is realized by a spring pull rod...
